SAMUEL O. TUERK, OF SYRAOUSE, NEW YORK.

BURNISHER.

SPECIFICATION forming part of Letters Patent No. 449,391, dated March 31, 1891.

Application filed December 2, 1889. Serial No. 332,203. No model.)

To all whom, t may concern:

Be it known that I, SAMUEL O. TUERK, of

' Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Burnishers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in burnishers, and has for its object the production of a cheap and efficient construction of the same class described and claimed in my previous patent, No. 427,937, dated May 13, 1890.

To this end it consists, essentially, in a suitable feeding-roller, a rotary hollow burnishing-roller, a hollow heating-chamber beneath said roller having inlet and outlet openings, whereby a continuous current of hot air is circulated therethrough, a heater or burner for producing said current, and a jacket between said roller and heating-chamber.

My invention also consists in the detail, construction, and arrangement of the parts, all ashereinafter more particularly described, and pointed out in the claims.

In describing` this invention reference is had to the accompanying drawings, forming a part of the specifica-tion, in which like letters indicate corresponding parts in all the views.

Figure l represents an elevation of my improved burnisher in operative position. Fig. 2 is a longitudinal vertical section of the parts, as illustrated in Fig. l, with the lower part of the supporting standards broken away. Fig. 3 is a transverse sectional view taken on line a' oc, Fig. 2. Fig. el. is a transverse sectional view taken on line y y, Fig. 2. Fig. 5 is a detail view illustrating the catch for retaining the feed-roller of my burnisher at any point of its adjustment; and Fig. G is a modified form of my device, in which the outlet or vent openings of the heating-chamber are placed at the ends thereof and register with like openings in the supporting-frame or standards of the burnisher.

In my aforesaid patent No. 427,937, I have shown a construction of burnisher in which a heated currentis continuously passed through the burnishing-roller for heating the same, but in this device, although the general arrangement and construction of the parts are similar to that embodied in the aforesaid patent, the manner of heating the burnishingroller is different, since, as will be hereinafter described, the heat is derived by radiation from a jacket interposed between the top of a suitable heating-chamber and the burnishing-roller.

The frame A, supporting the parts of my improved burnisher, is of any desirable form, size, and construction, but is here illustrated as a pair of legs A', journaled in which is the burnishing-roller B, which is heated by means of a suitable lamp or burner C. This heater may be of any ldesirable form and construction, but is here illustrated as an ordinary gasheater connected to the gas-pipe C.

In order to render the burnisher highly eficient, it is necessary that the same heat quickly and that all direct contact of the heat with the burnishing-surface of the burnishing-roller be absolutely prevented, and these desirable results are effected by my improved mechanism.

Partially surrounding and extending beneath the burnishing-roller B is the heatingchamber D, provided at the upper part thereof with an opening D', in which the lower half of the burnishing-roller revolves, and provided at the lower part with an opening` D2 of suitable size and contour to fit the top of the burner C. Incasing the lower part of the roller and mounted in the upper opening D of the heating-chamber D is the jacket E, which closely tits said opening D', in order to absolutely prevent the escape of gas therefrom.

Provided in the upper part of the heatingchamber D are suitable vent or outlet openings tZ, arranged, preferably, at the separate ends, in order to produce an even healing of said chamber and aconsequent uniform transmission of heat to the roller B. These openings are of suitable size to provide the desired draft, and it will be readily understood that when the heater or burner is in operation a heated current is continuously drawn through said heating-chamber, thus heating` thejacket E and also the burnishingroller B. This construction of heatingcham ber is of especial value, since as the heater closely fits the inlet-opening thereof all entrance of cold air is absolutely prevented, and the outlet of the heated current is effected only after the same has been drawn upward to the top of said chamber.

As in my aforesaid patent, in order to IOO more perfectly lit the opening D2 to the heater K a of the frame and carrying the opposite ends of the feeding-roller H. These cams are provided with the cam-face g and the concentric face g', formed with worm-teeth. These worm-teeth are engaged by worms I, mounted on the shaft', so that both are operated conjointly by the rotation of a suitable hand wheel or piece I', thus rendering` the movement of both sliding boxes exactly uniform. As in my aforesaid patent, it is necessaryto hold the adjusting mechanism at any point of its movement, and I provide the serrated plate or segment K, which is engaged by a spring-actuated dog 7o, secured to said shaft i.

At Fig. 6 I have illustrated a modified form of my burnisher, in which the vent-openings Z are provided in the separate ends of the heating-chambers, and are then registered with openings a, provided in the standards A. It will, however, be understood that there may be other changes made in the relative construction and arrangement of the parts of my invention. Hence I do not limit myself to their precise form. and construction.

In my previous patent, No. 427,937, of May 13, 1890, I have shown a burnisher having a somewhat similar construction of adjusting means for the roller, and I do not herein claim the construction shown in said previous patent. v

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isu l. In aburnisher, the combination of a burnisher-roller, a heating -chamber inclosing said roller,a heater for passing a heated current within said chamber, and an outlet-opening in said chamber, whereby a continuous heated current is forced through said chamber and the roller is heated, substantially as and for the purpose set forth.

2. In a burnisher, the combination of aburnishing-roller, 'a heating-chamber inclosing said roller, a heater forpassing a heated current into said heatingchamber, an outletopening in the chamber, whereby a continuous heated current is passed therethrough, and a jacket interposed between said roller and heating-chamber for preventing direct contact of the heat with the roller, substantially as and for the purpose specified. l The combination of the feed-roller, a hollow burnishing-roller, a heating-chamber inclosing Asaid roller, a heater for passing a heated current intoA said chamber, andan outlet-opening therein, whereby a continuous heated current is passed through said chamber, substantially as and for the purpose specitied.

4. In aburnisher, the combination of afeedroller, a hollow burnishing-roller, a heatingchamber inclosing said roller, a heater for passingaheated current of air into said chamber, an outlet-opening in said chamber forming a vent therefor, and a jacket interposed between said hollow burnishing-roller and heating-chamber, whereby. the direct contact with the roller of the heated current within the said chamber is prevented, substantially as and for the purpose set forth.

5. In a burnisher, the combination of a burnishing-roller, a heating-chamber inclosing said roller, a heater for passing a heated current within said chamber, an outlet-opening in said'chamber forming a vont therefor and insuring a constant current through the chamber, and a thermometer attached to said heating-chamber for indicating the heat thereof, substantially as and for the purpose set forth.

6. In aburnisher, the combination of an adj ustable roller, a heating-box for said roller, a rotary cam bearing upon said box, wormteeth upon said cam, and a worm for engaging said teeth, substantially as and forv the purpose specified.

7 In a burnisher, the combination of an adjustable roller, separate journal-boxes for the opposite extremities of said roller, rotary cams bearing upon said boxes, worm-teeth provided upon said cams, worms for engaging said teeth, and a connection between said rollerwheels, whereby both are operated uniformly at the same time, substantially as and for the purpose specified.

8. Ina burnisher, the combination of an adjustable roller, a heating-box for said roller, a rotarycam bearing upon said box, wormteeth upon said cam, a worm for engaging said teeth, a rack or notched plate, and a dog 'or catch for engaging said rack or plate, substantially as and for the purpose set forth.

9. In a burnisher, the combination of an adjustable rollen-separate j ournal-boxes for the opposite extremities of said roller, rotary cams bearing upon said boxes, worm-teeth provided upon said cams, worms for engaging said teeth, a connection between said roller-wheels, whereby both are operated uniformly at the same time, a rack or notched plate, and a dog or catch for engaging said rack or plate, substantially as and for the purpose specified.
